Intermediate supporting structure for rigidity improving and shock absorption

Abstract

The invention discloses an intermediate supporting structure for rigidity improving and shock absorption. The structure includes an upper bracket, a lower bracket, a rubber widget and a bearing; the upper bracket and the lower bracket are semicircular and arranged in a buckled mode, the rubber widget is annular, the outer annular surface of the rubber widget is connected in a circular space formed after the upper bracket and the lower bracket are buckled in a clamping mode, the inner annular surface of the rubber widget is provided with a first groove, the bearing is arranged in the first groove, and raised ribs are uniformly arranged between the inner annular surface and the outer annular surface of the rubber widget. According to the intermediate supporting structure for rigidity improving and shock absorption, the situation that vibration of rear axles, a drive system and a vehicle body is intensified due to the vibration of a transmission shaft and the intermediate supporting structure is avoided, fire coupling with a road surface is avoided, on low-speed and high-speed road sections, the vibration noise of the whole vehicle is significantly reduced, and the purpose of reducing the vibration noise is achieved.

Description

technical field [0001] The invention relates to a supporting structure of a transmission shaft, in particular to an intermediate supporting structure for improving rigidity and shock absorption. Background technique [0002] For front-rear drive vehicles, in order to reduce the vibration of the transmission shaft, avoid the vibration of the rear axle, transmission system, and vehicle body due to the vibration of the transmission shaft and the intermediate support, and avoid coupling with the road surface excitation to achieve the purpose of reducing vibration and noise. It is often necessary to increase the radial stiffness of the intermediate support and the rigid body mode of the transmission shaft. [0003] For the current intermediate support structure, its rigidity is low. Stiffness can only be increased by increasing the hardness of the rubber. However, after the hardness is improved, it is difficult to assemble the intermediate support assembly, and it is difficult ...

Problems solved by technology

However, after the hardness is increased, it is difficult to assemble the intermediate support components, and it is difficult to realize the process

[0004] However, the structure at the mounting hole where the intermediate support is connected to the mounting bracket is mostly designed with pure metal, which is rigidly connected, which is not conducive to vibration reduction.
